What is the meaning of the English word 'frass'?

Answer 1

Solid excrement from insects is the meaning of the English word "frass." The English noun originates in the same-spelled German derivative of the infinitive fressen ("to feed or to gobble like an animal"). It currently refers to waste products from larval stages of insects and to the non-digested, non-eliminated refuse by-products of boring insects tunneling through wood.
